Summed series involving \,1F2 hypergeometric functions
Abstract
In a prior paper we found that the Fourier-Legendre series of a Bessel function of the first kind JN(kx) and of a modified Bessel functions of the first kind IN(kx) lead to an infinite set of series involving \,1F2 hypergeometric functions (extracted therefrom) that could be summed, having values that are inverse powers of the eight primes 1/(2i3j5k7l11m13n17o19p) multiplying powers of the coefficient k, for the first 22 terms in each series. The present paper shows how to generate additional, doubly infinite summed series involving \,1F2 hypergeometric functions from Chebyshev polynomial expansions of Bessel functions, and trebly infinite sets of summed series involving \,1F2 hypergeometric functions from Gegenbauer polynomial expansions of Bessel functions.
